Emulsified oil for hydraulic supports is a kind of functional oil specially developed for the hydraulic systems of hydraulic supports in underground coal mines. After being mixed with water in a certain proportion, it forms a stable emulsion, which is used as a hydraulic transmission medium in hydraulic support equipment to ensure that the hydraulic supports can operate reliably and efficiently. It plays a vital role in the support operations during coal mining.



It is applicable to the hydraulic systems of all kinds of underground hydraulic supports in coal mines. Meanwhile, it can also be used in the hydraulic transmission systems of other mining hydraulic equipment under similar working conditions.

Support OEM and ODM customization services.
Warm Tips: Customized production can be carried out based on customers' requirements. If you want to make a purchase, please contact us!
